Apekshit Sharma d69570a485 HBASE-18925 Update mockito dependency from mockito-all:1.10.19 to mockito-core:2.1.0 for JDK8 support.
Last mockito-all release was in Dec'14. Mockito-core has had many releases since then.

From mockito's site:
- "Mockito does not produce the mockito-all artifact anymore ; this one was primarily
aimed at ant users, and contained other dependencies. We felt it was time to move on
and remove such artifacts as they cause problems in dependency management system like
maven or gradle."
- anyX() and any(SomeType.class) matchers now reject nulls and check type.

Guanghao Zhang 00f2b18148 HBASE-19007 Align Services Interfaces in Master and RegionServer
Purges Server, MasterServices, and RegionServerServices from
CoprocessorEnvironments. Replaces removed functionality with
a set of carefully curated methods on the *CoprocessorEnvironment
implementations (Varies by CoprocessorEnvironment in that the
MasterCoprocessorEnvironment has Master-type facility exposed,
and so on).

A few core Coprocessors that should long ago have been converted
to be integral, violate their context; e.g. a RegionCoprocessor
wants free access to a hosting RegionServer (which may or may not
be present). Rather than let these violators make us corrupte the
CP API, instead, we've made up a hacky system that allows core
Coprocessors access to internals. A new CoreCoprocessor Annotation
has been introduced. When loading Coprocessors, if the instance is
annotated CoreCoprocessor, we pass it an Environment that has been
padded w/ extra-stuff. On invocation, CoreCoprocessors know how to
route their way to these extras in their environment.

See the *CoprocessoHost for how the do the check for CoreCoprocessor
and pass a fatter *Coprocessor, one that allows getting of either
a RegionServerService or MasterService out of the environment
via Marker Interfaces.

Removed org.apache.hadoop.hbase.regionserver.CoprocessorRegionServerServices

M hbase-endpoint/src/main/java/org/apache/hadoop/hbase/security/access/SecureBulkLoadEndpoint.java
 This Endpoint has been deprecated because its functionality has been
 moved to core. Marking it a CoreCoprocessor in the meantime to
 minimize change.

M hbase-rsgroup/src/main/java/org/apache/hadoop/hbase/rsgroup/RSGroupAdminEndpoint.java
 This should be integral to hbase. Meantime, marking it CoreCoprocessor.

M hbase-server/src/main/java/org/apache/hadoop/hbase/Server.java
 Added doc on where it is used and added back a few methods we'd
removed.

A hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/CoreCoprocessor.java
 New annotation for core hbase coprocessors. They get richer environment
 on coprocessor loading.

A hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/HasMasterServices.java
A hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/HasRegionServerServices.java
 Marker Interface to access extras if present.

M hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/MasterCoprocessorEnvironment.java
  Purge MasterServices access. Allow CPs a Connection.

M hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/RegionCoprocessorEnvironment.java
  Purge RegionServerServices access. Allow CPs a Connection.

M hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/RegionServerCoprocessorEnvironment.java
  Purge MasterServices access. Allow CPs a Connection.

M hbase-server/src/main/java/org/apache/hadoop/hbase/quotas/MasterSpaceQuotaObserver.java
M hbase-server/src/main/java/org/apache/hadoop/hbase/quotas/QuotaCache.java
  We no longer have access to MasterServices. Don't need it actually.
  Use short-circuiting Admin instead.

D hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/CoprocessorRegionServerServices.java
  Removed. Not needed now we do CP Env differently.

M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
  No need to go via RSS to getOnlineTables; just use HRS.

And so on. Adds tests to ensure we can only get at extra info
if the CP has been properly marked.

HBASE-18350 RSGroups are broken under AMv2
- Table moving to RSG was buggy, because it left the table unassigned.
  Now it is fixed we immediately assign to an appropriate RS
  (MoveRegionProcedure).
- Table was locked while moving, but unassign operation hung, because
  locked table queues are not scheduled while locked. Fixed.
- ProcedureSyncWait was buggy, because it searched the procId in
  executor, but executor does not store the return values of internal
  operations (they are stored, but immediately removed by the cleaner).
- list_rsgroups in the shell show also the assigned tables and servers.

Apekshit Sharma 0c883a23c5 HBASE-17732 Coprocessor Design Improvements
------------------------------------------------------
TL;DR
------------------------------------------------------
We are moving from Inheritence
- Observer *is* Coprocessor
- FooService *is* CoprocessorService
To Composition
- Coprocessor *has* Observer
- Coprocessor *has* Service

------------------------------------------------------
Design Changes
------------------------------------------------------
- Adds four new interfaces - MasterCoprocessor, RegionCoprocessor, RegionServierCoprocessor,
  WALCoprocessor
- These new *Coprocessor interfaces have a get*Observer() function for each observer type
  supported by them.
- Added Coprocessor#getService() to base interface. All extending *Coprocessor interfaces will
  get it from the base interface.
- Added BulkLoadObserver hooks to RegionCoprocessorHost instad of SecureBulkLoadManager doing its
  own trickery.
- CoprocessorHost#find*() fuctions: Too many testing hooks digging into CP internals.
  Deleted if can, else marked @VisibleForTesting.

------------------------------------------------------
Backward Compatibility
------------------------------------------------------
- Old coprocessors implementing *Observer won't get loaded (no backward compatibility guarantees).
- Third party coprocessors only implementing Coprocessor will not get loaded (just like Observers).
- Old coprocessors implementing CoprocessorService (for master/region host)
  /SingletonCoprocessorService (for RegionServer host) will continue to work with 2.0.
- Added test to ensure backward compatibility of CoprocessorService/SingletonCoprocessorService
- Note that if a coprocessor implements both observer and service in same class, its service
  component will continue to work but it's observer component won't work.

------------------------------------------------------
Notes
------------------------------------------------------
Did a side-by-side comparison of CPs in master and after patch. These coprocessors which were just
CoprocessorService earlier, needed a home in some coprocessor in new design. For most it was clear
since they were using a particular type of environment. Some were tricky.

- JMXListener - MasterCoprocessor and RSCoprocessor (because jmx listener makes sense for
  processes?)
- RSGroupAdminEndpoint --> MasterCP
- VisibilityController -> MasterCP and RegionCP

These were converted to RegionCoprocessor because they were using RegionCoprocessorEnvironment
which can only come from a RegionCPHost.
- AggregateImplementation
- BaseRowProcessorEndpoint
- BulkDeleteEndpoint
- Export
- RefreshHFilesEndpoint
- RowCountEndpoint
- MultiRowMutationEndpoint
- SecureBulkLoadEndpoint
- TokenProvider

Balazs Meszaros c48dc02b76 HBASE-18106 Redo ProcedureInfo and LockInfo
Main changes:
- ProcedureInfo and LockInfo were removed, we use JSON instead of them
- Procedure and LockedResource are their server side equivalent
- Procedure protobuf state_data became obsolate, it is only kept for
reading previously written WAL
- Procedure protobuf contains a state_message field, which stores the internal
state messages (Any type instead of bytes)
- Procedure.serializeStateData and deserializeStateData were changed slightly
- Procedures internal states are available on client side
- Procedures are displayed on web UI and in shell in the following jruby format:
  { ID => '1', PARENT_ID = '-1', PARAMETERS => [ ..extra state information.. ] }

Do a pass with dependency:analyze; remove unused and
explicity list the dependencies we exploit.
Remove the parent dependencies set which had junit, mockito,
log4j, and findbugs annotations (had to put junit back
temporarily in subsequent version of this patch TODO). Listing in
parent set meant these libs were dependencies for all modules
which in practice was not the case. Edited all modules so
those that need any from this parent set now do explicit listing.

Ran the dependency:analyze over the project. Acted on most
suggested removals and requests for explicit listing. Some
grey areas remain around transitives that come in with
hadoop -needs better excludes, another project- and that
the dependency:analyze tool is not always accurate in its
reporting.

Michael Stack d5c6e11016 HBASE-17908 Upgrade guava
Pull in guava 22.0 by using the shaded version up in new hbase-thirdparty project.

In poms, exclude guava everywhere except on hadoop-common. Do this so
we minimize transitive includes. hadoop-common is needed because hadoop
Configuration uses guava doing preconditions.

Everywhere we used guava, instead use shaded so fix a load of imports.

Michael Stack 3975bbd008 HBASE-14614 Procedure v2 - Core Assignment Manager (Matteo Bertozzi) Move to a new AssignmentManager, one that describes Assignment using a State Machine built on top of ProcedureV2 facility.
This doc. keeps state on where we are at w/ the new AM:
https://docs.google.com/document/d/1eVKa7FHdeoJ1-9o8yZcOTAQbv0u0bblBlCCzVSIn69g/edit#heading=h.vfdoxqut9lqn
Includes list of tests disabled by this patch with reasons why.

Based on patches from Matteos' repository and then fix up to get it all to pass cluster
tests, filling in some missing functionality, fix of findbugs, fixing bugs, etc..
including:

    1. HBASE-14616 Procedure v2 - Replace the old AM with the new AM.
    The basis comes from Matteo's repo here:
    689227fcbf

    Patch replaces old AM with the new under subpackage master.assignment.
    Mostly just updating classes to use new AM -- import changes -- rather
    than the old. It also removes old AM and supporting classes.
    See below for more detail.

    2. HBASE-14614 Procedure v2 - Core Assignment Manager (Matteo Bertozzi)
    3622cba4e3

    Adds running of remote procedure. Adds batching of remote calls.
    Adds support for assign/unassign in procedures. Adds version info
    reporting in rpc. Adds start of an AMv2.

    3. Reporting of remote RS version is from here:
    ddb4df3964.patch

    4. And remote dispatch of procedures is from:
    186b9e7c4d

    5. The split merge patches from here are also melded in:
    9a3a95a2c2
    and d6289307a0

We add testing util for new AM and new sets of tests.

Does a bunch of fixup on logging so its possible to follow a procedures' narrative by grepping
procedure id. We spewed loads of log too on big transitions such as master fail; fixed.

Fix CatalogTracker. Make it use Procedures doing clean up of Region data on split/merge.
Without these changes, ITBLL was failing at larger scale (3-4hours 5B rows) because we were
splitting split Regions among other things (CJ would run but wasn't
taking lock on Regions so havoc).

    Added a bunch of doc. on Procedure primitives.

    Added new region-based state machine base class. Moved region-based
    state machines on to it.

    Found bugs in the way procedure locking was doing in a few of the
    region-based Procedures. Having them all have same subclass helps here.

    Added isSplittable and isMergeable to the Region Interface.

    Master would split/merge even though the Regions still had
    references. Fixed it so Master asks RegionServer if Region
    is splittable.

    Messing more w/ logging. Made all procedures log the same and report
    the state the same; helps when logging is regular.

    Rewrote TestCatalogTracker. Enabled TestMergeTableRegionProcedure.

    Added more functionality to MockMasterServices so can use it doing
    standalone testing of Procedures (made TestCatalogTracker use it
    instead of its own version).

    Add to MasterServices ability to wait on Master being up -- makes
    it so can Mock Master and start to implement standalone split testing.
    Start in on a Split region standalone test in TestAM.

    Fix bug where a Split can fail because it comes in in the middle of
    a Move (by holding lock for duration of a Move).

    Breaks CPs that were watching merge/split. These are run by Master now
    so you need to observe on Master, not on RegionServer.

    Details:

    M hbase-client/src/main/java/org/apache/hadoop/hbase/ClusterStatus.java

    Log and doc on workings. Bug fixes.

    A hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/RemoteProcedureDispatcher.java
    Dispatch remote procedures every 150ms or 32 items -- which ever
    happens first (configurable). Runs a timeout thread. This facility is
    not on yet; will come in as part of a later fix. Currently works a
    region at a time. This class carries notion of a remote procedure and of a buffer full of these.

    M hbase-protocol-shaded/src/main/protobuf/Admin.proto b/hbase-protocol-shaded/src/main/protobuf/Admin.proto
    Add execute procedures call ExecuteProcedures.

    M hbase-protocol-shaded/src/main/protobuf/MasterProcedure.proto

    M hbase-server/src/main/java/org/apache/hadoop/hbase/master/MasterRpcServices.java
    Extract version number of the server making rpc.

    A hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignProcedure.java
    Add new assign procedure. Runs assign via Procedure Dispatch.
    There can only be one RegionTransitionProcedure per region running at the time,
    since each procedure takes a lock on the region.

Michael Stack dc1065a85d HBASE-14614 Procedure v2 - Core Assignment Manager (Matteo Bertozzi)
Move to a new AssignmentManager, one that describes Assignment using
a State Machine built on top of ProcedureV2 facility.

This doc. keeps state on where we are at w/ the new AM:
https://docs.google.com/document/d/1eVKa7FHdeoJ1-9o8yZcOTAQbv0u0bblBlCCzVSIn69g/edit#heading=h.vfdoxqut9lqn
Includes list of tests disabled by this patch with reasons why.

Based on patches from Matteos' repository and then fix up to get it all to pass cluster
tests, filling in some missing functionality, fix of findbugs, fixing bugs, etc..
including:

1. HBASE-14616 Procedure v2 - Replace the old AM with the new AM.
The basis comes from Matteo's repo here:
689227fcbf

Patch replaces old AM with the new under subpackage master.assignment.
Mostly just updating classes to use new AM -- import changes -- rather
than the old. It also removes old AM and supporting classes.
See below for more detail.

2. HBASE-14614 Procedure v2 - Core Assignment Manager (Matteo Bertozzi)
3622cba4e3

Adds running of remote procedure. Adds batching of remote calls.
Adds support for assign/unassign in procedures. Adds version info
reporting in rpc. Adds start of an AMv2.

3. Reporting of remote RS version is from here:
ddb4df3964.patch

4. And remote dispatch of procedures is from:
186b9e7c4d

5. The split merge patches from here are also melded in:
9a3a95a2c2
and d6289307a0

We add testing util for new AM and new sets of tests.

Does a bunch of fixup on logging so its possible to follow a procedures' narrative by grepping
procedure id. We spewed loads of log too on big transitions such as master fail; fixed.

Fix CatalogTracker. Make it use Procedures doing clean up of Region data on split/merge.
Without these changes, ITBLL was failing at larger scale (3-4hours 5B rows) because we were
splitting split Regions among other things (CJ would run but wasn't
taking lock on Regions so havoc).

Added a bunch of doc. on Procedure primitives.

Added new region-based state machine base class. Moved region-based
state machines on to it.

Found bugs in the way procedure locking was doing in a few of the
region-based Procedures. Having them all have same subclass helps here.

Added isSplittable and isMergeable to the Region Interface.

Master would split/merge even though the Regions still had
references. Fixed it so Master asks RegionServer if Region
is splittable.

Messing more w/ logging. Made all procedures log the same and report
the state the same; helps when logging is regular.

Rewrote TestCatalogTracker. Enabled TestMergeTableRegionProcedure.

Added more functionality to MockMasterServices so can use it doing
standalone testing of Procedures (made TestCatalogTracker use it
instead of its own version).

Add to MasterServices ability to wait on Master being up -- makes
it so can Mock Master and start to implement standalone split testing.
Start in on a Split region standalone test in TestAM.

Fix bug where a Split can fail because it comes in in the middle of
a Move (by holding lock for duration of a Move).

Breaks CPs that were watching merge/split. These are run by Master now
so you need to observe on Master, not on RegionServer.

Details:

M hbase-client/src/main/java/org/apache/hadoop/hbase/ClusterStatus.java
Takes List of regionstates on construction rather than a Set.
NOTE!!!!! This is a change in a public class.

A hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/RemoteProcedureDispatcher.java
Dispatch remote procedures every 150ms or 32 items -- which ever
happens first (configurable). Runs a timeout thread. This facility is
not on yet; will come in as part of a later fix. Currently works a
region at a time. This class carries notion of a remote procedure and of a buffer full of these.
"hbase.procedure.remote.dispatcher.threadpool.size" with default = 128
"hbase.procedure.remote.dispatcher.delay.msec" with default = 150ms
"hbase.procedure.remote.dispatcher.max.queue.size" with default = 32

M hbase-client/src/main/java/org/apache/hadoop/hbase/shaded/protobuf/ProtobufUtil.java
Add in support for merge. Remove no-longer used methods.

M hbase-protocol-shaded/src/main/protobuf/Admin.proto b/hbase-protocol-shaded/src/main/protobuf/Admin.proto
Add execute procedures call ExecuteProcedures.

M hbase-protocol-shaded/src/main/protobuf/MasterProcedure.proto
Add assign and unassign state support for procedures.

M hbase-server/src/main/java/org/apache/hadoop/hbase/client/VersionInfoUtil.java
Adds getting RS version out of RPC
Examples: (1.3.4 is 0x0103004, 2.1.0 is 0x0201000)

M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java
Remove periodic metrics chore. This is done over in new AM now.
Replace AM with the new. Host the procedures executor.

Extract version number of the server making rpc.

A hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignProcedure.java
Add new assign procedure. Runs assign via Procedure Dispatch.
There can only be one RegionTransitionProcedure per region running at the time,
since each procedure takes a lock on the region.

Apekshit Sharma ce64e7eb6e HBASE-17654 RSGroup refactoring.
Changes contain:
- Making rsGroupInfoManager non-static in RSGroupAdminEndpoint
- Encapsulate RSGroupAdminService into an internal class in RSGroupAdminEndpoint (on need of inheritence).
- Change two internal classes in RSGroupAdminServer to non-static (so outer classes' variables can be shared).
- Rename RSGroupSerDe to RSGroupProtobufUtil('ProtobufUtil' is what we use in other places). Moved 2 functions to RSGroupManagerImpl because they are only used there.
- Javadoc comments
- Improving variable names
- Maybe other misc refactoring

Apekshit Sharma f444b3b542 HBASE-17312 Use 'default' keyword in coprocessor Observer interfaces to get rid of 'Base...Observer' implementations. Some javadoc improvements too.
Reason for refactor:
In cases where one might need to use multiple observers, say region, master and regionserver; and the fact that only one class can be extended, it gives rise to following pattern:

public class BaseMasterAndRegionObserver
  extends BaseRegionObserver
  implements MasterObserver

class AccessController
  extends BaseMasterAndRegionObserver
  implements RegionServerObserver

were BaseMasterAndRegionObserver is full copy of BaseMasterObserver.

There is an example of simple case too where the current design fails.
Say only one observer is needed by the coprocessor, but the design doesn't permit extending even that single observer (see RSGroupAdminEndpoint), that leads to copy of full Bas
e...Observer class into coprocessor class leading to 1000s of lines of code and this ugly mix of 5 main functions with 100 useless functions.

Javadocs changes:
- Adds class comments on 'default' methods and expectations.
- Adds explanaiton of Exception handling in Observers' class comment. Removes redundant @throws before each function.
- Improves javadocs for a bunch of functions
- deletes empty @params in a bunch of places
